I've had good and bad experiences with Delta camshafts, mostly with their profiles not being ideal for the engine. I'm building a F22A1 turbo setup, forged internals, sleeved and built head setup. Sadly it has been a while since my last F22 setup, and now there doesn't seem to be much options available. Seems to be either Delta or Bisi, and Bisi quoted me some long lead time for a camshaft and said the 1.2 is the only option, no more 2.X option.

If you have experience with the Delta camshaft, did you make good power with it? It seems like the 272 works well for lower boost, but I haven't seen a before/after dyno with a Delta so I don't know how well it's helping. That had been my concerns in the past. I'm shooting for at least 400whp+. I talked to Web cams, and they don't have any standard profiles, so they would have to make a custom one, again long lead time.

 

The stock cam will fall flat around 5500-5800rpm, even with a nice tubular manifold. From what I've seen the 272 will extend that about 500-600rpm before it starts to fall flat. Even with a nice manifold and turbo, you can expect it to be completely out of steam before 7000rpm. With a log style it will be even less efficient. The cam will help but ultimately you're going to be limited by the single cam design. For 400+, you should be fine.

It's going to be pretty difficult to find a lot of information about this nowadays so good luck. I don't really know of anyone still modifying them to this degree.

 

Found this thread and just wanted to chime to hopefully make it stay alive in case any of the OG CB7 guys find it too. 26 years old and finally got the car I wanted in high school. Seems a lot of the market that existed then is dying off in favor of the h22 and K24 market. But regardless, if any of these parts and knowledge are still out there I want to be around for them.
